A forum thread on GameFAQs has indications that Risen 2: Dark Waters may be the latest game to ship with what's supposed to be future DLC included on the retail disc. The thread outlines the discovery, and spawns one of those heated discussions over the ethics of making content on the game disc dependant on a future. Thanks Blend Games.
